8 Claimsr My invention relates to pickup Itools and more particularly to the kind used in concrete forms for the removal of the spacer elements between the side walls of the concrete molding form.

My invention further provides a tool of length and width sucient to enable the operator to dislodge the .spacer elements from their positions between the side wallsof the concrete forms during the pouring of the concrete and then pick up the same.

Another' object of the invention is to provide a tool which will readily facilitate the dislodgment of the spacer elements by either bumper or grabbling means or by picking up the same after they have become dislodged.

Another object of the invention resides in the provision of a tool of this class that can be economically produced and which may be readily handled efciently for the picking up of debris in the bottom of forms such as leaves, shavings, paper, etc,

With these and other objects the invention will become apparent from references to the following description of an embodiment thereof and in which description reference will be had to the accompanying drawing forming part of the specication. Referring to the drawing;

Figure 1 is an isometric perspective of the pickup tool.

Figure 2 is a side elevation of the tools jaws picking up paper debris.

Figure 3 is a side elevation of a spacer element being grappled for dislodgment and removal from its position between the walls of the concrete form.

Figure 4 is a front view of the pickup tool.

Figure 5 is a side View of Figure 4.

Referring to the drawing A represents a handle to which the pickup tool B is secured by fastening means C. The pickup tool B is provided with a face plate I whose sides are bent up to form btunper member legs 2 which are connected by impact striker 3. The pickup tool B is provided with side brackets D which sustain a pivot support E to which is secured .the movable jaw F. The movable jaw F is at its inner end formed with a loop connection 4 while the outer end is provided with a bite plate 5.

Positioned in the sides of the jaw F is a roller support 6 which sustains the roller l. Alt a predetermined point along the length of the pickup tool is a rockable clevis G whose side arms G are rockably secured to the pickup tool B by the holding means 8. Upon the face of the pickup tool B there is positioned a U shaped spring secured to the face plate I and held securely by the fastening means 9. The U shaped springs free leaf I resting Well under the jaw supporting member E, permits its free spring end II to contact the roller l, and throw the jaw F into closvvIl ing position as indicated by the arrow in Figure 5.

The clevis G will hold the loop connection 4 of the jaw F in locked position when the clevis top I2 is projected over the loop member 4 of 10 the jaw and thereby hold the jaw F arrested until released. The clevis G is further provided with a rotatable control member I 3 to which is secured a plunger I 4 extending through the impact striker 3 to a sensitive control end I5. Along 35 the length of the plunger I 4, there is provided a bracket I6 extending up from the plunger I4 to a strut rod Il secured to the plunger I4 at a point closer to the clevis .control member I3. The bite plate member 5 is provided with an edge I8 20 which will cooperate in gripping with the bite edge I9 of the impact striker 3.

VIn operation, assuming the user was operating the pickup tool within a concrete form to pick up debris prior to ithe casting of the concrete; 25 he would lower the tool into the form, and assuming that the debris was paper, the tool jaws would be set as in Figure 1 and Figure 5 with a plunger I5 extending through the impact striker so that the edges I8 and I9 would rest over the 30 debris to be picked up. A slight pressure downward upon the tool pole would force the plunger I4 inward, rotating the clevis G about its fastening means 8, lso as to free the loop 4 from its holding from under the top member I2 of the 35 clevis G. The releasement would free the compression forces of the spring S held atop the member I so that the springs free end II would exert its force upon roller 1 held rotatable upon a shaft 6 positioned between the jaw sides F and 40 force the jaw F outward at the locking end as indicated by arrow in Figure 5.

The jaw F being rockable upon the shaft E would close the space between the jaw edges I8 and I9 and pick up the debris as is best illus- 45 trated in Figure 2. By the lifting of the tool from within the form and the opening of the jaw on the outside of the form, the debris may be released. Should it be desired to use the tool `as a ram for the removal of spacers, the same 50 can be left in an open position and used as a ram rod using the impact striker edge 3 and the member 5 as bumper edges. Or by the resetting of the tool as shown in Figure 1 and Figure 5, the tool can be used for direct grabbling of the ber, locking means engaging spacers within the form by straddling the spacer so that the top end of the spacer will contact the bracket I6. Any downward pressure upon the handle will tend to push the plunger bracket I6 and its associated I4 inward so as to rotate the clevis G upon its fastening 8 and release the loop member 4 of the jaw F which will in turn clampl the spacer tightly within the pickup tool for removal.

I claim:

1. A pickup tool for removing the side wall spacer elements from a concrete molding form, comprising a U shaped metallic head having an impact striking surface to disengage side wall spacer elements, impact head holding means, a gripping jaw member pivotally supported by said holding means, a spring supported by said holding means in engagement with said jaw member, a rockable locking means for said jaw member, and a plunger rod extending through said impact striking surface and operative to release said locking means from the gripping jaw member.

2. A pickup tool for removing side wall spacer elements from a concrete molding form, comprising a jaw head having an impact striking surface to disengage side wall spacer elements, holding means for said jaw head, a jaw member pivotally supported by said head holding means in opposition to said impact head, rockable locking and releasing means vfor said pivoted jaw member, a spring supported by said holding means and in tension against said pivoted jaw member, and a slidable plunger rod extending through the impact head and operable to release said locking and releasing means from said pivotally supported jaw for the purpose set forth.

3. A pickup tool for removing side Wall spacer elements from a concrete molding form, comprising a U shaped metallic head having an impact striking surface to disengage spacer elements, holding means for said metallic head, a jaw member pivotally supported by said holding means to cooperate with said metallic head, a spring tensioned against said pivoted jaw memwith said pivoted jaw member and holding the jaw from said impact striking to release said locking means for forth.

4. A pickup tool of the class described comprising a base, a fixed jaw member carried by said base and having an impact striking surface, a spring tensioned jaw member pivotally supported by said base, locking means normally holding said pivoted member turned on its pivot away from said impact striking surface, and impact actuated means for releasing said locking means from said pivoted membe 5. A pickup tool of the class described comprising a fixed jaw member formed with an impact surface, a jaw member pivotally supported in opposition to said fixed jaw member, a spring means to turn said pivotal jaw member toward the fixed jaw member, a rockable bracket normally engaging with said pivoted jaw member, and holding said member turned away from the fixed jaw, and a control rod extending through the impact head of said xed jaw member actuatable to release said bracket from said jaw member.
